It hath seemed to me, most high and mighty prince, our dread king and sovereign, so important and weighty a matter to undertake a history of the great and valiant actions which our Portuguese have performed in the discovery and conquest of India, that I often thought to relinquish the attempt. But as these noble deeds were principally undertaken and performed for the glory of Almighty God, the conversion of the barbarous nations to the Christian faith, and the great honour of your highness; and as, by the power and mercy of the Omnipotent, such fortunate success has been granted to these famous enterprises, I have been encouraged to proceed. I therefore trust entirely to the aid and comfort of the divine goodness in publishing this work, giving the glory thereof to God alone, and its earthly praise to your excellent highness, and the king Don Manuel your father, of famous and happy memory. Although these glorious deeds are well known and spread abroad over the world, they yet cannot be sufficiently made manifest unless set forth in writing, by means of which their memory may endure for ever, and remain always as if present to the readers; as history hath perpetuated the actions of the Greeks and Romans which are of such high antiquity. Of other transactions, nothing inferior to theirs, perhaps even far greater, which have been performed by other nations, there is little or no memory, because these do not remain recorded by history: Such are those of the Assyrians, Medes and Persians; of the Africans against the Romans; of the Suevi against Julius Caesar; of the Spaniards in recovering their country from the Moors; and principally of these invincible and pious kings of Portugal, your glorious ancestors, Don Alonso Henriques, Don Sancho his son, and Don Alonso, who acquired the kingdoms of Portugal and Algarve by great and wonderful deeds of arms. Of all which, there hardly remaineth any memory, for want of having been duly recorded by writing. So likewise of those actions which have been performed in India, only as it were of yesterday, the exact memory of them is confined to four persons; and if they were to die, all remembrance of these transactions must have ended to their great dishonour. Considering these things, I resolved to record these noble deeds which the subjects of your highness have performed in the discovery and conquest of India, which have never been surpassed in valour, or even equalled, in any age or country. Leaving all mention of the conquests of Cyrus and other barbarians, and even taking into the account the deeds of Alexander, so famous over all the world, which are as nothing compared to what has been performed since India became frequented by the Portuguese, no more than a dead lion can be likened to one alive.
